#+OPTIONS: latex:t
#+LATEX_HEADER: \usepackage{bussproofs}
Hello Nick, hello everybody
Before using your suggestion of debugging, I have made another test to
convert formulas made with different latex packages into png images for
a html file.
At the beginning of my org file:
#+LATEX_HEADER: \usepackage{fitch}
#+LATEX_HEADER: \usepackage{bussproofs}
#+OPTIONS: tex:imagemagick
All formulas used with the equation environment have a nice png image,
and the Fitch proofs also.
But that is not the case with proofs in Gentzen tree style created via
bussproofs.sty : the png images are corrupted.
That's strange because it works well with LaTeX export and even with
latex-preview-image and org-htmlize. This image of implication
elimination rule in my gnus-message should be nice:
\begin{prooftree}
\AxiomC{$A \to B$}
\AxiomC{$A$}
\RightLabel{\scriptsize{$\to E$}}
\BinaryInfC{$B$}
\end{prooftree}
I am afraid to be not competent enough to use correctly the debugger
that you suggest, but it is probably again a problem my setup or
something missing in my headers and not a bug somewhere.
Best wishes,
Jo.
